VALVE FOR GAS-METERS.

SPECIFICATION forming part of Letters Patent No. 429,383, dated June 3, 1890.

Application filed December 9, 1889. Serial No. 333,024- (No model.)

To all whom it may concern.-

Be it known that I, HUGH LOGUE, a citizen of the United States, and aresident of Philadelphia, Pennsylvania, have invented certain Improvements in Valves for Gas-Meters, of which the following is a specification.

The object of my invention is to so construct the valve-operating mechanism for gas-meters that the connecting-rod will be as near the face-line of the valve as possible, insuring easy and accurate working of the valve without waste or leakage, as fully described hereinafter, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of my improved valve. Fig. 2 is a longitudinal section of the same. Fig. 3 is a longitudinal section, drawn to an enlarged scale, of part of the connecting-rod. Fig. 4 is a section on the line 1 2, Fig.

A is the carrying-plate of the meter; B, the valve-seat; D, the valve of the usual D pattern, adapted to slide on the seat, which is provided with the usual ports I) 1). Projecting from each end of the valve are guiderods E E','adapted to bearings e e, secured to the body of the meter. These guide-rods E are on a line as near the line of the bearing-surface 0c of the valve as possible, so as to keep the valve to its seat.

Secured to the rod E is a pivot-pin f, to which is secured-a connecting-rod F, which is attached to the crank-shaft of the meter. This connecting-rod is of the peculiar form shown in Figs. 1, 3, and 4, and has two arms nearer the face of the same than heretofore, and at the same time the guide-rods E E, being straight, enable me to grind the valve-face Without twisting the rods and while the rods are in position on the valve.

Heretofore it has been deemed necessary in making valves for gas-meters to bend the rods E to a position below the level of the face of the valve, in order to have the line of the connecting-rod as near the valve-face line as possible, and consequently if this rod is put in position on the valve prior to grinding it has to be bent out of line and after grinding bent into line again, this tampering with the rod after being once placed on the valve being very objectionable and likely to cause the valve to leak; but by constructing the valve as shown I am enabled to have the line of the connecting-rod as nearthe faceline of the valve as possible and to have an even bearing for the valve, the bearing-block passing through the opening 1' in the connecting-rod allowing for this alignment.

Iclaim as my invention The combination,in a valve for gas-meters, of the valve D, straight guide-rod E therefor, and bearing-block e for said guide-rod, with a connecting-rod F pivoted to said valve and to the crank-shaft of the meter, and having arms 9 g, formingan orifice i, into which the bearing-block e extends,substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HUGH LOGUE.
